Monitoring user terminal applications using performance statistics for combinations of different reported characteristic dimensions and values

ABSTRACT

An application analysis computer receives reports from user terminals which contain application performance metrics and dimensions having values characterizing the applications and the user terminals. Statistics for each different one of the performance metrics across the reports are generated for repeating time intervals. One of the statistics that has changed between two of the time intervals by an amount that satisfies a defined rule is identified, and the associated performance metric is selected for analysis. For each combination of a different one of the dimensions and a different one of the values occurring for the dimension, a statistic is generated for the selected performance metric associated with the combination, and a counter is incremented that tracks a number of occurrences of the combination among the reports. Sets of the statistic and the counter for particular ones of the combinations that satisfy an action rule are identified.

BACKGROUND

The present disclosure relates to computing systems, and, in particular, to management of user terminals, applications, and/or application servers.

Increasingly, users install a myriad of different types of application programs (also commonly referred to as “applications” and “apps”) on user terminals having widely varying software and hardware characteristics. For example, users can select from among several million different applications available on various application servers for downloading to cellular telephones (sometimes called “smart phones”), tablet computers, laptop computers, and other types of user terminals for processing. Over a billion Apple IOS user terminals and Android user terminals are presently being used throughout the world.

Mobile analytics is an emerging technology that seeks to measure performance of applications processed by user terminals. Using mobile analytics processes, user terminals can collectively generate millions of performance reports every day for processing by an analysis computer. Analysis of the performance reports can require expensive and complex hardware and software resources and the analysis can be prone to excessive error or reduced usefulness due to the tremendous number of combinations of differing application characteristics and user terminal characteristics from which individual reports are generated.

The approaches described in the Background section could be pursued, but are not necessarily approaches that have been previously conceived or pursued. Therefore, unless otherwise indicated herein, the approaches described in the Background section are not prior art to the claims in this application and are not admitted to be prior art by inclusion in the Background section.

SUMMARY

Some embodiments of the present disclosure are directed to a computer program product that includes a non-transitory computer readable storage medium including computer readable program code embodied in the medium that when executed by a processor of an application analysis computer causes the processor to perform operations. The operations include receiving, from user terminals, reports containing performance metrics for applications processed by the user terminals and characteristic dimensions having values characterizing the applications and the user terminals. Statistics for each different one of the performance metrics across the reports are generated for repeating time intervals. One of the statistics for one of the performance metrics that has changed between two of the time intervals by an amount that satisfies a defined rule is identified. The one of the performance metrics is selected for analysis. For each combination of a different one of the characteristic dimensions and a different one of the values occurring for the characteristic dimension, a statistic is generated for the selected one of the performance metrics associated with the combination of the characteristic dimension and the value among the reports, and a counter in incremented to track a number of occurrences of the combination of the characteristic dimension and the value among the reports. Sets of the statistic and the counter for particular ones of the combinations of the characteristic dimension and the value that satisfy an action rule are identified. A message is generated which contains information that is defined based on the sets.

DETAILED DESCRIPTION

In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of embodiments of the present disclosure. However, it will be understood by those skilled in the art that the present invention may be practiced without these specific details. In other instances, well-known methods, procedures, components and circuits have not been described in detail so as not to obscure the present invention. It is intended that all embodiments disclosed herein can be implemented separately or combined in any way and/or combination.

Some embodiments of the present disclosure are directed to improved processes for analyzing performance metrics reported by user terminals. Although the reports can be received from a tremendous number of combinations of differing application characteristics and user terminal characteristics, various embodiments disclosed herein may operate to generate and organize the performance metrics from the reports in ways that facilitate use of less expensive and/or reduced complexity hardware and software resources.

FIG. 1 is a block diagram of a system 100 for analyzing operation of applications processed by user terminals using reported performance metrics and statistics generated from selected performance metrics associated with combinations of different characteristic dimensions and different values among the reports, in accordance with some embodiments of the present disclosure. The system 100 includes an application analysis computer 150 which receives reports from user terminals 102 a-n through wireless network communications (e.g., radio access networks (RAN) 130 a-130 n) and/or wired network communications via a data network 120. The data network 120 may be a private network and/or a public network such as the Internet. One or more of the user terminals 102 a-102 n may communicate through the radio access networks 130 a-130 n using one or more wireless communication protocols that may include, but are not limited to, 3GPP Long Term Evolution (LTE), WLAN (IEEE 802.11), WiMax, Bluetooth, etc.

The user terminals 102 a-102 n can download application programs from the application server 140. The application server 140 may, for example, include an Apple application store server (e.g., iTunes), an Android application store server (e.g., Google Play and/or Amazon Appstore), and/or a Window application store server (e.g., Microsoft Windows Store). Although the application analysis computer 150 has been illustrated as being separate from the application server 140, some or all of the functionality of the application analysis computer 150 disclosed herein may be combined with the application server 140 or another computer node (“network node”) communicatively connected to the network 120.

The application programs may include gaming programs, spreadsheet programs, multimedia programs, word processing programs, database programs, presentation programs, etc. The application programs may be selected from among several million different applications available from application servers for downloading to many different types of user terminals. The user terminals 102 a-102 n may include cellular telephones (sometimes called “smart phones”), tablet computers, laptop computers, and other types of electronic communication devices configured for processing applications.

Although FIG. 1 illustrates a certain number of system components for ease of illustration and explanation, it is to be understood that embodiments of the present disclosure are not limited to the illustrated configuration but instead are intended to encompass any configuration capable of carrying out at least some of the operations described herein.

Each of the user terminals 102 a-102 n (individually referred to as “user terminal 102”) may include an instrument encapsulation module 108 that operates to generate reports containing performance metrics for an application program 106 (“application”) processed by processor of the user terminal 102 and characteristic dimensions having values characterizing the application 106 and the user terminal 102. The instrument encapsulation module 108 may “wrap around” the application program 106 to intercept or otherwise observe application programming interface (API) calls from the application program 106 to other application programs 104 processed by the user terminal 102, an operating system 110 processed by the user terminal 102, and/or other software/hardware resources of the user terminal 102.

As used herein, an “API request” can be any signaling occurring from one to another software application that may be performed using a defined syntax and one or more parameters (e.g., data structure, object classes, and/or variables) to obtain data therefrom and/or to provide data thereto. For example, SOAP and REST service requests can be performed using a defined API library of remote calls or other types of API requests.

FIG. 2 is a flowchart of operations that may be performed by the application analysis computer 150 for receiving, storing, and generating statistics from reports regarding operation of applications (e.g., application program 106) on user terminals 102 a-n in accordance with some embodiments of the present disclosure.

Referring to FIG. 2, reports are received (block 200) from user terminals. Different types of applications and/or versions of the same application may generate reports at different time intervals, such as every minute, hour, day, week, month, or year, and the reporting time intervals may vary over time responsive to one or more defined conditions being satisfied and/or responsive to a command message from the application analysis computer 150 and/or the application server 140. A report contains a performance metric for the application 106 processed by the user terminal 102 and characteristic dimensions having values characterizing the application 106 and the user terminal 102. Raw data contained in the reports can be stored (block 202) in a memory, such as in a structured database residing across an array of networked data servers. Statistics are separately generated (block 202) for each different one of the performance metrics across the reports for each of the repeating time intervals. The statistic may be generated by numerically combining (e.g., averaging) values of one of the performance metrics in all reports received during one of the time intervals.

FIG. 3 is a flowchart of operations that may be performed by the application analysis computer 150 for generating and using statistics for combinations of different reported characteristic dimensions and values in accordance with some embodiments of the present disclosure.

Referring to FIG. 3, the application analysis computer 150 identifies one of the statistics for one of the performance metrics that has changed between two of the time intervals by an amount that satisfies a defined rule. For example, the raw data stored in the memory and the statistics generated therefrom can be accessed (block 300) by the application analysis computer 150, and a decision (block 302) is made whether one of the performance metrics occurring between two time interval satisfies the defined rule. If so, the application analysis computer 150 selects (block 304) the one of the performance metrics for analysis. Although the operations of FIG. 3 are described in the context of a single performance metric being selected (block 304), in some other embodiments more than one performance metric is selected based on observing changes with those performance metrics that satisfy one or more of the defined rules.

For each combination of a different one of the characteristic dimensions (operational loop indicated by block 308) and a different one of the values occurring for the characteristic dimension (operational loop indicated by block 310), a statistic is generated (block 312) for the selected one of the performance metrics associated with the combination of the characteristic dimension and the value among the reports, and a counter is incremented (block 314) which tracks a number of occurrences of the combination of the characteristic dimension and the value among the reports.

In the operational loops indicated by blocks 308 and 310, for each combination of a different one of the characteristic dimensions and a different one of the values occurring for the characteristic dimension, a statistic can be generated for the selected one of the performance metrics associated with the combination of the characteristic dimension and the value among the reports, based on selecting a combination of a unique characteristic dimension from among the different ones of the characteristic dimensions and a unique value from among the different ones of the values occurring for the unique characteristic dimension among the reports, and generating a combined statistic based on numerically combining the selected one of the performance metrics associated with the unique characteristic dimension and the unique value among the reports. The operations for selecting a combination and for generating a combined statistic are repeated for other unique combinations of the characteristic dimensions and the values among the reports. Each of the combined statistics is associated with a different one of the combinations. The operations for selecting a combination and for generating a combined statistic may be repeated for other unique combinations of the characteristic dimensions and the values among the reports until a last unique combination of the characteristic dimensions and the values has been selected and used to generate a combined statistic.

The statistic for the selected one of the performance metrics associated with the combination of the characteristic dimension and the value among the reports, may be generated (block 312) based on numerically combining the selected one of the performance metrics associated with the combination of the characteristic dimension and the value among the reports without including any of the selected one of the performance metrics among the reports which is not associated with the combination of the characteristic dimension and the value. The numerical combining may be performed by averaging values of the selected one of the performance metrics associated with the combination of the characteristic dimension and the value among the reports without including any of the selected one of the performance metrics among the reports which is not associated with the combination of the characteristic dimension and the value. The numerical combining may alternatively be performed by generating trend information based on content of the selected one of the performance metrics associated with the combination of the characteristic dimension and the value among the reports without including any of the selected one of the performance metrics among the reports which is not associated with the combination of the characteristic dimension and the value.

Sets of the statistic and the counter for particular ones of the combinations of the characteristic dimension and the value that satisfy an action rule, are identified (block 316). It is noted that the sets may be generated by a single pass through the raw data from the reports to identify the sets, which may allow the application analysis computer 150 to process a tremendous number of reports from a tremendous number of combinations of differing application characteristics and user terminal characteristics using less expensive and/or reduced complexity hardware and software resources.

A message is generated (e.g., block 318 or block 320) which contains information that is defined based on the sets. The application analysis computer 150 may generate a notification message identifying the sets of the statistic and the counter for particular ones of the combinations of the characteristic dimension and the value that satisfy the action rule, and communicate the notification message towards a network node via the data network 120. The application analysis computer 150 may alternatively or additionally generate a notification message that identifies characteristics of an application and a user terminal 102 which may have problematic operation determined based on the action rule, and communicate the notification message towards the application server 140 via the data network 120. The application server 140 may respond to the notification message by disabling further download of a particular application program to particular ones of the user terminals 102 a-n identified based on the sets reported in the notification message, and/or by generating a message to the particular ones of the user terminals 102 a-n offering an alternative version of the particular application program and/or a substitute application program for replacing the particular application program. The counter(s) may be used to determine whether, for example, a sufficient number of instances of the identified application operations (e.g., problems) have been identified such that an remedial action or other action should be initiated.

Still alternatively or additionally, the application analysis computer 150 may generate a notification message that identifies characteristics of an application which may have problematic operation determined based on the action rule, and communicate the notification message towards user terminals that process applications having the identified characteristics.

In the embodiment of FIG. 3, the application analysis computer 150 may communicate (block 318) a notification message containing information identifying the sets to the network node, such as the application server 140, another application retailer, and/or an application developer's computer. Alternatively or additionally, the application analysis computer 150 may control (block 320) operation of selected ones of the user terminals 102 a-n, selected ones of the applications, and/or application server 140 based on content of the identified sets. When the application analysis computer 150 communicates a command to selected user terminals 102, the instrument encapsulation module 108 can adapt operation of the application program 106 based on the command, such as to disable operation of the application program 106 and/or to display a message on a display device of the selected user terminals 102.

As explained above, each report can contain a performance metric for the application program 106 being processed by the user terminal 102, and characteristic dimensions having values characterizing the application program 106 and/or the user terminal 102. The performance metrics may be generated by the reporting encapsulation module 108 which encapsulates the application program 106 to monitor operation of a present instance of the application program 108 processed by the user terminal 102 and related utilization of resources of the user terminal 102. The characteristic dimensions may characterize features and other characteristics of the application program 106 and the user terminal 102 which may be separate or independent from how a present instance of the application program 106 is presently operating while processed by the user terminal 102.

The performance metrics may include any one or more of the following:

-   -   1. application program 106 utilization of user terminal 102         processor resources;     -   2. application program 106 utilization of user terminal 102         memory resources;     -   3. application program 106 utilization of user terminal 102         network interface resources;     -   4. application program 106 communication latency through the         data network 120 and/or the radio access network 130;     -   5. communication latency between the application program 106 and         the application program 104;     -   6. application program 106 response latency to defined input;     -   7. application program 106 wait time for receipt of user input;     -   8. rate of information displayed by the application program 106         on a display device of the user terminal 102;     -   9. duration of operational use of the application program 106 by         the user;     -   10. time between instances of application program 106 use;     -   11. time of day and/or day or week of instances of application         program 106 use;     -   12. velocity of the user terminal 102 while processing the         application program 106;     -   13. control gestures or other inputs provided by a user as input         to control application program 106 operation;     -   14. which features and/or sequences of features of the         application program 106 are used;     -   15. how often features and/or sequences of features of the         application program 106 are used;     -   16. number of features or levels of features of the application         program 106 accessed or completed by a user;     -   17. events characterizing inefficient or ineffective operational         use of the application program 106;     -   18. user selection of additional in-application features (e.g.,         download/activate);     -   19. user selection of other application programs (e.g.,         download/activate) while using the application program 106;     -   20. information characterizing data communications between the         application program 106 and another application program, an         operating system 110, and/or to other software/hardware         resources of the user terminal;     -   21. events indicative of errors or undesirable operation of the         application program 106;

The application analysis computer 150 may generate a separate statistic for each of the performance metrics contained in the report, e.g., one statistic for application program 106 utilization of user terminal 102 processor resources, another statistic for application program 106 utilization of user terminal 102 memory resources, etc.) A statistic may be generated by numerically combining (e.g., averaging) values of one of the performance metrics in all of the reports (e.g., block 204) or in only reports having a defined combination of the characteristic value and the value (e.g., block 314), which are received during a selected one of the time intervals. Resource utilization may be reported in one or more of the reports as a percentage value, as an indicated resource level among a plurality of defined resource levels, etc.

The characteristic dimensions and corresponding values (bracketed) may include one or more of the following:

-   -   1. location geographic coordinates (values among defined list of         defined regions);     -   2. location city (values among defined list of cities);     -   3. location state (values among defined list of states);     -   4. location country (values among defined list of countries);     -   5. application identifier (values among list of defined         identifiers);     -   6. application version (values among list of defined versions);     -   7. application functionality (values among list of defined         functions);     -   8. application display update rate capabilities (values among         list of defined capabilities);     -   9. application preferred or required memory capacity (values         among list of defined capacities);     -   10. application preferred or required processor capacity (values         among list of defined capacities);     -   11. application preferred or required network communication         capacity (values among list of defined capacities);     -   12. application preferred or required co-executed other         application(s) (values among list of defined applications);     -   13. user terminal identifier (values among list of defined         identifiers);     -   14. user terminal manufacturer (values among list of defined         manufacturer identifiers);     -   15. user terminal model (values among list of defined models);     -   16. user terminal processor type (values among list of defined         types);     -   17. user terminal memory capacity (values among list of defined         capacities);     -   18. user terminal communication capability (values among list of         defined communication capabilities);     -   19. user terminal operating system type (values among list of         defined types);     -   20. user terminal operating system version (values among list of         defined versions);     -   21. user terminal display resolution (values among list of         defined resolutions);     -   22. user terminal camera resolution (values among list of         defined resolutions);     -   23. user terminal screen refresh rate capability (values among         list of defined capabilities);     -   24. user terminal speaker volume capability (values among list         of defined capabilities);     -   25. wireless carrier registered with user terminal (values among         list of defined carriers);     -   26. user selected user-interface language (values among list of         defined languages);     -   27. user information (values among list of defined names,         attributes, etc.);     -   28. operational settings selected by the user for operation of         the application program 106 and/or changes over time in the user         selected operational settings;     -   29. gaming challenges or levels of the application program 106         selected by the user from among available challenges or levels;     -   30. other application programs active in background while user         is using the application program 106; and     -   31. occurrence of one or more defined control gestures performed         by the user through a user interface of the user terminal 102 to         interface with the application program 106 and/or frequency of         occurrence of the one or more defined control gestures.

Further example operations are now described in the context of the nonlimiting embodiment of FIG. 4, which is a flowchart of operations that may be performed by the application analysis computer 150 for generating statistics for combinations of different reported characteristic dimensions and values relating to CPU utilization and application response latency performance metrics. The operations may be used to identify possible problematic application operation.

Referring to FIG. 4, the application analysis computer 150 accesses (block 400) statistics of raw data of reports. In the example embodiment, the reports are received from user terminals across North America, and each report contains M performance metrics, N characteristic dimensions having O different values. For the reasons explained above, the numbers M, N, and O can be large. As will be explained below, the operations provided in FIG. 4 can identify problematic operations by a particular application processed by a particular version of an operating system on a particular brand of user terminal operating within a particular city, which may assist with determining the underlying bases for the problem.

Statistic values for CPU utilization and application response latency are identified (block 402) as each having changed more than threshold amounts defined by a rule. CPU utilization and application response latency are therefore selected (block 404) as performance metrics for further analysis. The application analysis computer 150 reads (block 406) the raw data of the reports from the memory, e.g., the structured database.

For each combination of a different one of the characteristic dimensions (operational loop indicated by block 408) and a different one of the values occurring for the characteristic dimension (operational loop indicated by block 410), a statistic is separately generated (block 412) for each of CPU utilization and application response latency associated with the combination of the characteristic dimension and the value among the reports. A separate counter is incremented (block 414) which tracks a number of occurrences of the combination of the characteristic dimension and the value among the reports (i.e., one counter tracks occurrences of the CPU utilization associated with the combination, and another counter tracks occurrences of the application response latency associated with the combination).

The application analysis computer 150 identifies (block 416) for each report, a characteristic dimension for an application name having an associated identifier value, a characteristic dimension for an operating system having an associated value for a version number of Android, a characteristic dimension for a user terminal brand with a value identifying the manufacturer, a characteristic dimension for city location with a value identifying a city within Canada where the user terminal is located. The application analysis computer 150 identifies based on the sets of the statistics and the counters for the combinations of characteristic dimensions and values that satisfy a performance alert rule, that applications associated with the combinations have been observed consuming excessive CPU resources and having excessive application response latency. In this manner, when an application is operating improperly due to, for example, operational requirements of an application not being satisfied by local telecommunications performance and/or compatibility issues, the sets of statistics and associated combinations of characteristic dimensions and values can enable the application analysis computer to quickly pinpoint potential bases for the application operational problems and the extent of the problem. Application retailers may thereby restrict or prevent usage of the application by user terminals that are unable to properly execute the application and/or may deploy a different version of the application or a substitute for the application to those user terminals. Application developers may be notified of the bases of the application operational problem so that future versions of the application may avoid or compensate for such operation.

In the embodiment of FIG. 4, the application analysis computer 150 may communicate (block 418) an alert message containing information identifying the sets to a network node, such as the application server 140 or another application retailer, and/or an application developer's computer. Alternatively or additionally, the application analysis computer 150 may control (block 420) operation of the problematic application on user terminals that are processing that application, and may control the application server 140 to disable further download of the problematic application with identified version number to the particular brand of user terminals located in the identified cities within Canada.

FIG. 5 is a combined data flow diagram and flowchart of operations by a user terminal 102, the application analysis computer 150, and the application server 140 in accordance with some embodiments of the present disclosure.

Referring to FIG. 5, the application program 106 performs an API call (block 500) to the other application program 104. The reporting encapsulation module 108 intercepts (block 502) the API call. The reporting encapsulation module 108 forwards (block 504) the API call to the other application program 104, which receives and processes (block 506) the API call. The other application program 104 may communicate a response message which is intercepted and forwarded (block 504) through the reporting encapsulation module 108 to the application program 106.

The reporting encapsulation module 108 measures (block 508) performance metrics based on monitoring the API calls, hardware resource utilization, etc, and generates (block 510) a report containing performance metrics and characteristic dimensions having values such as described above. The report is communicated (block 512) toward the application analysis computer 150. The operations for measuring, generating reports, and communicating reports are performed repetitively according to a defined time interval, which may vary over time responsive to occurrence of a condition defined by a rule and/or responsive to a message from the application analysis computer 150 and/or from the application server 140.

The application analysis computer 150 performs operations (block 514) shown in FIG. 1, FIG. 2, and/or FIG. 3 in accordance with some embodiments. The application analysis computer 150 may communicate a notification message to control (block 516) operation of application program 106 on the user terminal 102. Application analysis computer 150 may alternatively or additionally communicate a notification message to control (block 518) downloading of the application program, which version of the application program is available for downloading, etc, such as described above.
